Model comparison of Delta and Omega masses in a covariant Faddeev approach

Published 14 Dec 2011 in hep-ph and nucl-th | (1112.3214v1)

Abstract: We compute the vector-meson, nucleon and delta/omega-baryon masses and their evolution with the current-quark mass using a covariant generalized Bethe-Salpeter equation approach. The interaction kernel is truncated to a dressed gluon exchange. We study the model dependence of our results with the quark-gluon dressing to assess the validity of the truncation.
